  3. Tertiary prevention

  4. Both B and C

The method of reproduction in unicellular organisms like amoeba and bacteria in which they split into two equal halves and produce new ones is called ............

  1. Fragmentation

  2. Binary fission

  3. Budding

  4. Spore formation


Correct Option: B
Explanation:

In binary fission, parent cell divides into two equal halves called daughter cells. Daughter cells are identical to each other and to their parent cell. Organisms like the amoeba, bacteria, euglena, etc. exhibit binary fission. During multiple fission, the organism divides itself into numerous daughter cells.

So, B is the correct option.

In animal cells, cytokinesis involves 

  1. Separation of sister chromatids

  2. Contraction of ring of microfilaments

  3. Depolymerisation of kinetochore microtubules

  4. Protein kinase that phosphorylates other enzymes


Correct Option: A

In animal cytokinesis, cleavage occurs with the help of

  1. Microtubules

  2. Spindle fibres

  3. Microfibrils

  4. Microfilaments


Correct Option: D

Cytochalasin B is a drug isolated from moulds. It blocks the formation of contractile microfilaments. Which of the following aspects of the cell cycle would be most disrupted due to this ?

  1. Cleavage furrow formation

  2. Attachment of kinetochore to spindle fibres

  3. Spindle fibre formation

  4. Cell elongation during anaphase


Correct Option: C
Explanation:

Spindle formation is mainly done by centrioles. It helps in separation of chromosomes during cell division. Cytochalasin B is a cell-permeable mycotoxin. It inhibits cytoplasmic division by blocking the formation of contractile microfilaments due to which cell is unable to maintain the desired number of chromosomes and leads to numerical abberations.
